of wheels, and particularly car wheels for railway rolling stock.Heretofore it has been proposed to make all st'eel car wheels by certainpressing, rolling and sha ingoperations in which a wheel is producehaving the rim or tireintegralwith the web and hub. It is also of courseold to form the tires sepairately and bolt or otherwise mechanicallysecur'ethcn to the rim of a locoxiiotivewheel.

Mylinvention is desi 'ned to provide a steel car wheel which may bemore'cheaply made than the ordinary all-steel car wheel, and which shallalso have a. better quality of metal in the tread and flange portions.

ln carrying out; my invention I form the hub and web of the wheel ofsteel or wrought metal either bycasting, pressing, shaping, or in anyother desirable manner. 1 form the tread and flange portions of'thewheel as aseparate operation, such portions being preferably providedwith an inwardly-extending annular rib or flange. I then electricallyweld the rib portion of the tire or rim to the I whee web ortion of thebody, thus forming a l which may be cheaply. made, 'whjile very durableandstrong. I

In-the drawings, 2 represents the hub and 3' the continuous web of asteel wheel, these partsbeing formed by casting orin any other desirableWay. The outer edge portion 4 of the web is preferably machinei to givea smoothsurface. and preferably extends at an angle to the axis of thehub or to the general plane of the wheel.

I 5 is the rim portion having the usual tread and the flange 6,- andbeing provided with an inwardly-projectin annular rib 7. This tire.

or rim portion wit 1 its rib or inwardly-prolectmg flange may be formedby the ordinary ethods for'rolling tires, such as used in making tiresfor locomotive wheels. The inner" edge portion of the tread rib orflange is then referably machined at an angle corresponr mgto the edgeangle of the web, and the parts may then be fitted together andelectrically welded by the use of weil-l nown methods. The welding maybe carried out through the entire circumference of the joint at oneoperation, or the-welding may be carried out successively in successivesections. During the welding operation, the joint may be firmly pressedtogether, and the bevel of the surfaces enables them to be. brought intointimate contact.

T he advantages of smy invention. result from the separate formalioii ofthe rim or tire and thebody 'portion proper, and the electrical;welding.of these parts.) In this way the tire or rim may be rolled or otherwisetreated so as to give the clniracteristies desirable in regard to wear,shocks, etc.;

while the body portion may be formed of another character of steel ortreated in such way as to give the characteristics desired for the huband body.

leted is an all-steel wheel without any oltcd or riveted joints, thusgiving a strong,

lOflg-llVOt-l wheel having the desired characteristics of metal in thedil'lerent portions thereof. 1

The wheel may be provided Wlill spokes m which case the: rib of the rimmay be continuous or interrimied. The shape and size of the parts may bevaried, and many other variations may be made in the wheel and the stepsof its formation, without departing from the spirit and scope of myinvention.

1. As a new article of manufact ure. :1 wheel composed of a centerportion and a rim poifion, thetwo'portions being, separately andindependently formed and united by an electrical weld extending" betweenand throughout thc directly contacting; surfaces thereof: substz'mtiallyas described. I
